Abstract: METHOD AND APPARATUS FOR REPLACING A SECTION OF TUBING                   ABSTRACT OF THE DISCLOSURE    A method and apparatus for replacing a damaged or defective section of a length of original piping or tubing located within a structure such as the turbine of a jet engine wherein access to the tubing is limited, and replacing such damaged section with a new section of tubing comprises inserting a cutter mounted at one end of a flexible shaft into the interior of the original tubing and rotating the shaft to cut out and remove the damaged section of tubing leaving at least one stub section of original tubing.  The stub sections of original tubing are then prepared for welding or brazing to a section of replacement tubing with a series of tools each mounted to an elongated shaft to permit manipulation of such tubes onto the cut ends of the stub section of original tubing through an access opening in the structure where the tubing is located.  These tools include a chamfering tool for forming a chamfer on both the inner and outer surfaces of the wall of the stub section, a deburring tool for removing burrs and surface irregularities from the outer surface of the stub section and a polishing tool for polishing the outer surfaces.  The replacement section of tubing is connected to the stub section of original tubing by inserting a hollow mounting sleeve welded or brazed to the replacement section of tubing over the end of the stub section so that the end edge of the stub section engages a brazing ring carried in the interior of the hollow mounting sleeve against the end edge of the replacement section of tubing.  The elongated nozzle of an acetylene torch is then inserted into the replacement section of tubing and heats the brazing ring to form a fluid-tight joint between the replacement section of tubing, the stub section of original tubing and the mounting sleeve.

Abstract: APPARATUS FOR DETECTING THE PASSAGE OF MULTIPLE           SUPERPOSED SHEETS ALONG A FEED PATH           Abstract of the Disclosure A multiple sheet detection apparatus includes first and second cooperating rollers (12, 14), the second roller (14) being movable away from the first roller (12) in response to the passage of a single or multiple sheet between the rollers (12, 14).  Voltage generating means (42) produce an output voltage which varies linearly with movement of the axis of the second roller relative to the axis of the first roller (12).  Data processing means sample this voltage a predetermined number of times over one complete revolution of the first roller (12), first with no sheet present and then with a single or multiple sheet passing between the rollers (12, 14), to produce first and second values which are respectively representative of the sums of the voltages sampled during each such revolution.  The first value is subtracted from the second value to produce a third value on the basis of which the number of sheets corresponding to the second value is determined.

Abstract: an  apparatus  is disclosed for providing capillary electrophoresis,   which   includes  an  electronically controlled  valve  system for automatically introducing a  sample  into  the  capillary by means of a vacuum at the  end  of  the  capillary  tube.    This approach of sucking   in  the  sample  is  extremely  accurate  and reproducible,   and   results  in  a  minimum  of  band broadening.      Furthermore,  it  enables  the  entire capillary    electrophoresis   system   to   be   easily automated.   An automated temperature control system is provided   which   enables   the   temperature  of  the capillary  tube  (and  hence the solvent/solute system) to   be   controlled  during  electrophoresis,  thereby very   directly   controlling  pH  and  electrophoretic mobility.   In  another  embodiment,  the capillary is prewashed  and  equilibrated  to  achieve substantially zero  charge on the capillary wall, thereby essentially eliminating   electroosmotic   flow  and  substantially improving resolution.

Abstract: The deformability measurement chamber is subdivided by a foil into two chamber spaces. The foil has a passage opening, the diameter of which is smaller than the diameter, at rest, of a red blood corpuscle. A static pressure gradient exists between the two chamber spaces, so that a flow takes place from one chamber space to the other. In the region of the passage opening there is situated on each side of the foil an electrode, which is connected to an alternating voltage source. In order to achieve a measurement signal which is approximately one order of magnitude greater, at a given alternating voltage frequency, a current-measuring operational amplifier is disposed in the connecton of one electrode to the voltage source.
